FAQ

What CSV formats are supported?

Supports standard CSV (comma-delimited), TSV (tab-delimited), and custom delimiter formats. Auto-detects encoding (UTF-8, GBK, Latin-1, etc.), supports quoted fields and escape characters.

How are nested objects handled in JSON to CSV?

Three strategies available: flattening (dot notation like user.name), first-level extraction only, or custom mapping rules. AI automatically recommends the best flattening approach.

Can it handle large files?

Yes. Uses streaming technology supporting files up to 100MB. Large files are processed server-side with download links provided. Also supports chunked upload and resume.

Are data types automatically converted?

Yes. AI intelligently recognizes numbers (integer/float), dates/times, booleans (true/false/yes/no), null values, and maintains correct data types in JSON output.

Does it support batch conversion of multiple files?

Yes. Upload multiple files for batch conversion with ZIP download. Can also configure unified conversion rules applied to all files.
